The Tour de France is an annual bicycle race that is considered by many to be one of the world’s great sporting events.
Since it was first run in 1903, the Tour has seen many changes in route, distance, equipment used, and the rewards on offer for the winner.
For over a hundred years the beautiful countryside of France has been the backdrop to this multi-stage race that is now contested over a period of around three weeks every July.
This infographic takes a light hearted look at some of these changes and might even inspire you to get on a bike in your free time away from the classroom.
